Radeon R9 290 video card and Vegas Pro 13

[David Norman] “It is possible that with longer content the different would be magnified.”

Yes, if it’s shaving off seconds, then on longer content all those seconds could add up to minutes saved.

David,

Who made the R9 290 you have? Do you think it matters?

Hi John, this result doesn’t correlate with the previously held belief about older graphics cards only being able to use the Mainconcept for file renders and leveraging acceleration.

I can see in your own response a bit of surprise also.

Is it possible that version 13 has changed all of that?

[John Rofrano]

I would like to see someone else get the same results because no one else has seen the new graphics cards work with MainConcept AVC. I don’t know if David turned off GPU Acceleration of the timeline as well and perhaps that was the reason. The only true way to test is to only change the render options from CPU Only to GPU and nothing else. To my knowledge, Vegas Pro 13.0 has not change this. It’s the same old MainConcept AVC encoder.

Thanks for that, I agree, further tests with newer graphics cards and SV 13 would nail this one way or the other.

Can you try using the GPU-Z (you don’t even have to install it) to see the actual GPU utilization during rendering.

I have a HD 7970 (re-badged now as R9 280X) and it is not used at all in MainConcept encoding. It detects “OpenCL” in system, runs at 25% at beginning and after that, just short bursts (probably because real-time display).

What it uses it slightly, is the Sony encoder.

Agree.
SONY VEGAS PRO 13 with the same GPU (two AMD R9 290 running in Crossfire mode). Sony claims “dramatic” improvements against the “CPU only”. NOT true, as confirmed by GPUTweak monitor.
I started my 4K adventure with a SONY FDR-AX1 camera, configured a powerful workstation for editing with VEGAS and what I’m experiencing is that the two GPU are completely useless.
Hoping in a quick new release that fixes the problem.

Where does Sony claim that they support Crossfire mode because I don’t believe that they do.

Sony claims that supports OpenCL. That would take care of editing and your two GPU should be used in that mode (but not in crossfire, that’s for games only).
However, in my experience, the actual encoding process doesn’t make use efficiently of the latest AMD (or nVidia) GPU’s.
Not sure who’s blame it is.
MainConcept encoder was top of the line in 2010. But it wasn’t updated since.
However, since then, nVidia and AMD released some new hardware encoders and associated code for them – which Sony ignored completely.
Their updates are far and in between, no real feedback to community (it’s a wasteland there)… Last software update in 11/2014.

I am using in parallel CybeLink’s NLE and sadly they are much more on top of their game. They release updates, beta fixes, listen to their forums… And we are talking of even 4K hardware accelerated encoding here!

Sorry. I was not clear in my post. What is not true is the improvement in performance of Vegas Pro 13 when “GPU acceleration on video processing” is selected in VIDEO Preferencies.
“Crossfire” was mentioned as information about my workstation configuration.

Any suggestion about my video cards setting in order to activate the “GPU acceleration” are gratefully welcomed

Thanks in adavance
